Nearly 90 percent of African elephants in Gorongosa National Park, Mozambique, were murdered for ivory to finance their weapons in the country's civil war.
However, about one-third of women argue that the war did not develop their own counterparts in the generation born after the end of 1992, suggesting recent figures.
Male elephant teeth are larger and heavier, but with the increase of hunters, hunters have started to focus on females.
Joyce Poole, scientific director of a non-governmental organization called ElephantVoices, told National Geographic: e Over time, with the older population, you are beginning to acquire these very high non-women. Ele
Other countries also saw a change in the number of elephants.
In South Africa, 98 percent of 174 females in the Addo Elephant National Park were reported to have grown females in the early 2000s.
Hunting has also caused the size of the twilight in some overfished areas, such as southern Kenya.
Scientists say that elephants with this obstacle have changed how they behave.
The tusks are used to dig water or to pick up the bark of trees for food, so that mammals can travel far further to survive.
However, researchers say changes in the way elephants live may have greater implications for the ecosystems around them.
Ryan Long, a behavioral ecologist at the University of Idaho, told National Geographic: & # 39; All or all of these changes in behavior can lead to changes in the distribution of elephants across landscapes and these major changes. To have results for the rest of the ecosystem. & # 39;
The number of hairless elephants showed the lasting effect on humans.
